MCC-950

NLRP3 inflammasome activation inhibitor

Product Specifications

Background

NLRP3 (MCC950) was originally found to act as a cytokine release inhibitory drug (CRID), arresting activated monocytes and preventing activation of caspase-1(1). Discovered to be a novel inhibitor of the NLRP3 and AIM2 inflammasomes(2). Blocks canonical and noncanonical NLRP3 activation at nanomolar concentrations3. Inhibits interleukin 1β (IL-1β) secretion in vivo and attenuates the severity of experimental autoimmune encephalomyelitis (an MS disease model)(3). Disrupts the interaction between AIM2 and ASC in a reconstituted cell-free inflammasome(4). A valuable new tool for exploring the pathophysiology of NLRP3. It may contribute to additional alpha synuclein aggregation and cell loss in PD (5).
